I've been experimenting with having a varaible constant name, but failed
miserably... Can I please have a pointer?

What I'm trying to do is something like this:

$name = home;

Then read the constant IMG_HOME, like IMG_$name, I'm not sure I make myself
understood, but I hope so..

I dont think you can do that with a constant, but you can do this a 
normal variable:


$test = 'the value of test variable';
$var ='test';

echo $$var;
// will echo $test;

I stand under correction form my previous email, it can be done:

define('TEST', 'the value of constant TEST');

$var= 'TEST';

echo constant($var);

... and in that way, you can create the name of the constant as you please:

$VAR_IMG = 'HOME';
define('IMG_HOME', 'pic.jpg');
echo(constant('IMG_'.$VAR_IMG));
